WILLIAM MCINTYRE, OF HARTFORD, CONNECTICUT.

DOOR-HANGER.

SPECIFICATION forming part of Letters Patent No. 565,915, dated August 18, 1896. Application filed March 30, 1896. Serial No. 585,409. (No model.)

T0 at whom it may concern:

Be it known that I, WILLIAM MoINTYRE, a subject of the Queen of Great Britain, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and useful Improvement in Hangers for Sliding Doors, of which the following is a description, reference being had to the accompanying drawings, wherein Figure l is a diagrammatic front elevation view of the upper part of a pair of sliding doors equipped with said improvement. Fig. 2 is a view of the parts in vertical cross-section. Fig. 3 is a view of that face of one of the casing parts which contains half of the ball-chamber, with the balls therein. It also shows a reach, hereinafter described, attached to such casing part. Fig. 4 is an end view of the casing part shown in Fig. 3. Fig. 5 is a view, looking downward, upon that part of the reach which is below the dotted line y y of Fig.

- 3. Fig. 6 is a side view of the adjustable stop hereinafter described. Fig. 7 is an end view of such adjustable stop.

As indicated by the title, the improvement pertains to hangers for sliding doors, which are usually double or hung in pairs.

In the accompanying drawings the letter a denotes a support for the pair of double sliding doors. It is something which house-builders commonly call a header.

The letter 6 denotes headed bolts running vertically through the header or support a, with the nuts above the header and the bolthead below the same.

The letter 0 denotes the track-supports, pendent from the heads of the bolts b, like pendulums, so they are adapted to move or swing freely thereon. These track-supports sustain the track d through the medium of bolts and nuts CZ 61 The letters e denote two corresponding and cooperating casing parts fastened together by screws or the like. On the inside or inner face each bears the half of a continuous ballchamber e, a chamber that has two parallel flat runs with rounded ends.

The letter f denotes frictional balls contained in and together practically filling the ball-chamber. neath, so that the balls when in the lower run of the continuous chamber rest upon the track cl, a construction which gives anovel and peculiar ball-bearing track.

The letters 9 denote reaches attached to and extending downward from the casing containing the ball-chamber, with the lower part bent at an angle, as shown, so as to form a small level shelf. This so-called shelf carries an edge mortise h.

The letter 1 denotes bolts which at their necks '5, but not elsewhere, will slip sidewise into the edge mortise h. The heads of these bolts rest on the so-called shelves.

The letter 70 denotes nuts carried on the bolts last referred to and fastened into the top of the doors. The bolts 2' are adapted to move or swing pendulum-like from the shelves already referred to, and of course the doors have a similar freedom. By turning the bolts (see wrench-sockets t the height of the doors, or any part thereof, can be adjusted or regulated at pleasure.

The letters Z denote stops which can be adj usted anywhere along the length of the tracks, so as to determine the point to which a door shall be permitted to move, especially in its closing movement. They are provided with buffers m for the ball-casings to strike against.

I claim as my improvement-- In a traversing door hanger and carrier of the character described, the two-part ballrace, comprising the shells e 6, each having formed in its inner surface a continuous endless groove of semicircular cross section, which when united and secured together as shown match and form the continuous closed path for the balls f, all substantially as and for the purpose specified.

WILLIAM MOINTYRE.
